Alice and Bob have just met, and wonder whether they have a mutual friend. Each has 50 friends, out of 1000 other people who live in their town. They think that its unlikely that they have a friend in common, saying each of us is only friends with 5% of the people here, so it would be very unlikely that our two 5%s overlap. Assume that Alices 50 friends are a random sample of the 1000 people (equally likely to be any 50 of the 1000), and similarly for Bob. Also assume that knowing who Alices friends are gives no information about who Bobs friends are.
(a) Compute the expected number of mutual friends Alice and Bob have.
(b) Let X be the number of mutual friends they have. Find the PMF of X.
(c) Is the distribution of X one of the important distributions we have looked at? If so, which?
Answers
The expected number of mutual friends Alice and Bob have is 2.5.
In the scenario described, Alice and Bob each have 50 friends out of 1000 people in their town. They believe that the probability of having a mutual friend is low since each of them is only friends with 5% of the population. To calculate the expected number of mutual friends, we can consider it as a matching problem.
Alice's 50 friends can be thought of as a set of 50 randomly selected people out of the 1000, and similarly for Bob's friends. The probability of any given person being a mutual friend of Alice and Bob is the probability that the person is in both Alice's and Bob's set of friends.
Since the selection of friends for Alice and Bob is independent, the probability of a person being a mutual friend is the product of the probability that the person is in Alice's set (5%) and the probability that the person is in Bob's set (5%). Therefore, the expected number of mutual friends is \(0.05 * 0.05 * 1000 = 2.5\).

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 19)(0,19) and (3, 9728)(3,9728).
Answers
Answer:
y = 19*(8)^x
Step-by-step explanation:
We want to write an equation like:
y = a*b^x
That goes through the points (0, 19) and (3, 9728)
Then, when x = 0, we must have y = 19
Replacing those values in the equation we get:
19 = a*b^0 = a*1 = a
19 = a
Then the equation is:
y = 19*b^x
We also know that when x = 3, y = 9728
If we replace these values in the equation, we get:
9728 = 19*(b)^3
Let's solve this for b.
9728/19 = b^3
512 = b^3
∛512 = b = 8
Then the equation is:
y = 19*(8)^x

how are the graphs of y=2x+1 and y=-2x+1 similar? how are they different?
Answers
We want to compare the graphs of the two given linear equations, we will find that they have the same y-intercept but opposite slopes.
Linear equations:
A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
Here the two equations are:
y = 2*x + 1y = -2*x + 1So you can easily see that the two equations have the same y-intercept but opposite slopes.
So both of them pass through the point (0, 1) and both are lines, these are the similarities.
And the difference is that the slopes are just different.

What is Triangle?
A triangle is a closed, two-dimensional shape with three straight sides and three angles. It is one of the basic shapes in geometry and is used in many areas of mathematics, science, and engineering.
Since triangle ABC and triangle LMN have congruent corresponding sides, we know that they are similar triangles. This means that their corresponding angles are also congruent.
We are given that angle BAC is 58 degrees and angle MLN is 78 degrees. Since corresponding angles are congruent, this means that angle BAC is congruent to angle MLN.
Therefore, triangle ABC and triangle LMN are similar triangles with two pairs of corresponding congruent angles. This means that all corresponding sides are proportional.
Since AC = LN and BA = ML, we know that the ratio of the lengths of corresponding sides is:
AC / LN = BA / ML
Substituting the given values, we get:
1 = 1
This statement is true because the corresponding sides are congruent.
Therefore, the answer is: BA = LN.

Han and Clare are stuffing envelopes. Han can stuff 20 envelopes in one minute, and Clare can stuff 10 envelopes in one minute. They start working together on a pile of 1,000 envelopes. How long does it take them to finish the pile?
Answers
Answer:
it will take them 33 minutes and 20 seconds
Step-by-step explanation:
What we have here is that Han can stuff 20 envelopes in a minute while Clare can do 10 in a minute
So in a minute, they can jointly stuff 30 envelopes.
Mathematically we know that the number of time it will take to finish stuffing would be number of envelopes/ joint rate = 1000/30 envelopes per minute
So it will take 33 1/3 minutes
1/3 of a minute is same as 1/3 * 60 seconds = 20 seconds
So it will take them 33 minutes and 20 seconds

A popular resort hotel has 700 rooms and is usually fully booked About 8% of the time a reservation is canceled before the 6:00 pm deadline with no penalty What is the probability that at least 658 rooms will be occupied? Use the binomial distribution to find the exact value The probability is (Round to four decimal places as needed.) GITE
Answers
To find the probability that at least 658 rooms will be occupied in the popular resort hotel, we can use the binomial distribution. Rounded to four decimal places, the probability is approximately 0.9996.
The binomial distribution is appropriate in this case because each room reservation cancellation can be considered a Bernoulli trial with a success probability of 0.92 (since 8% of the time a reservation is canceled).
Let's denote X as the number of rooms occupied. We want to find P(X >= 658), which represents the probability that at least 658 rooms will be occupied. This can be calculated by summing the individual probabilities of having 658, 659, 660, and so on, up to the maximum possible number of successes, which is 700.
Using the binomial probability formula, P(X = k) = (n choose k) *\(p^k\) *\((1 - p)^(n - k)\), where n is the number of trials (700), k is the number of successes (658, 659, 660, ...), and p is the probability of success (0.92).
Now, let's calculate the individual probabilities and sum them up:
P(X >= 658) = P(X = 658) + P(X = 659) + P(X = 660) + ... + P(X = 700)
We can use a calculator or statistical software to perform these calculations. After calculating each individual probability using the binomial probability formula and summing them up, the result is the probability that at least 658 rooms will be occupied.
Rounded to four decimal places, the probability is approximately 0.9996. Therefore, there is a very high probability (99.96%) that at least 658 rooms will be occupied in the popular resort hotel, considering the cancellation rate and the total number of rooms.

Which ordered pair (x, y) satisfies the system of equations shown below?
9x - y = 63
x = y +7
Answers
Answer: (7, 0)
Step-by-step explanation:
We have the system of equations:
9*x - y = 63
x = y + 7
We can see that the "x" is isolated in the second equation, then we can replace it in the first equation to get:
9*x - y = 63
9*(y + 7) - y = 63
Now we have an equation that only depends on one variable, so we can solve it:
9*y + 63 - y = 63
8*y + 63 = 63
8*y = 63 - 63 = 0
y = 0/8 = 0.
Now we know the value of y, we can replace this in one of the initial equations to find the value of x, i will replace this in the second equation:
x = y + 7 = 0 + 7 = 7
Then the point that is a solution for the system of equations is (7, 0)
